Having problems with your Compaq P110 21" CRT Monitor ?

A really loud cracking noise, akin to a 'zap', and the screen distorts

\015 Compaq 21" CRT Monitor, Model P110\015\012\015\012This has only happened twice so far, but each time it scared me senseless. My monitor will work fine, sometimes for hours, sometimes for days, and randomly, the screen will distort, and there will be a relatively loud cracking noise, similar to a 'zap'. Then it all goes back to normal.\015\012\015\012Afraid that the matter will simply blow to bits, having my face bet he victim, I asked a few people about what precautions I should take to see that my nose doesn't get split in two by shards. One claimed that the absolute worst possible scenario was that it would set on fire. One told me it cannot blow up, unless you hit the CRT tube itself.\015\012\015\012Is there anything I should do about this? Is this normal? Will I have my facial features carved into a totemic ornament? Etc etc. ANY help would be grandly appreciated.\015

Answers :

This may be happening because the tube was not fully clean when sealed and some particles left inside are finding homes next to high voltage. or the power supply is beginning to fail and arcing internally where it finds shortcut electric paths inside capacitors or coils or it...whatever the problem...\015\012keep in mind the tube is under vacuum, so it may implode but not explode. However, an implosion, severe enough, can be dangerous as one of Newtons laws may kick in, something about momentum transfer blah blah blah. Inside a business office, this monitor would be replaced by the geek squad to prevent employee lawsuits. oh, to answer the question: NO, this is not normal. replace it. crt monitors are quite cheap right now. faces and vocal cords are quite expensive.
In that case is it possible its simply static building in the monitor? It it properly earthed off?
